Weathering of microplastics and interaction with other ...

The UV fraction of light irradiation plays a key role in MP weathering. UV radiation with a wavelength of 290–400 nm in sunlight has enough energy (299–412 kJ mol-1) to break the C C bond (284–368 kJ mol-1) and the C H bond (381–410 kJ mol-1) for most plastics (Kholodovych and Welsh, 2007).

Ultra-High Performance Concrete

Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve specified requirements.

SonaSpray "fc" will resist impact and abrasion without cracking or spalling, typical to any cementitious or plaster based materials. In areas where even high abrasion resistance may be desirable, SonaSpray "fc" Dura-K may be specified. This provides even greater bond and compressive strength without reducing the acoustical performance.

Bond Work Index - an overview | ScienceDirect Topics

The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

Tungsten carbide - Wikipedia

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing shells and jewellery.
